The effectiveness of interventions to prevent loneliness in the community-dwelling elderly population

Abstract Background Loneliness and social isolation have comparable health effects to widely acknowledged and established risk factors. Although the elderly are particularly affected, the effectiveness of interventions to prevent and/or mitigate social isolation and loneliness in the community-dwelling elderly is unclear. The aim of this review of reviews was to pool the findings of systematic reviews addressing the question of effectiveness. Methods Ovid MEDLINE®, Health Evidence, Epistemonikos and Global Health (EBSCO) were searched from January 2017 to November 2021. Two reviewers independently assessed each systematic review in two consecutive steps based on previously defined eligibility criteria and appraised the methodological quality using AMSTAR 2. One author extracted data from both systematic reviews and eligible studies; another checked this. We conducted meta-analyses to pool the study results. We report the results of the random-effects and common-effect models. Results We identified 5 systematic reviews containing a total of 30 eligible studies, 16 with a low or moderate risk of bias. Our random-effects meta-analysis indicates an overall SMD effect of 0.63 [95% CI: -0.10; 1.36] for loneliness and was unable to detect an overall effect of the interventions on social support [SMD: 0.00; 95% CI: -0.11; 0.12]. Discussion The results show interventions can potentially reduce loneliness in the non-institutionalised, community-dwelling elderly population living at home. As confidence in the evidence is low, rigorous evaluation is recommended. Key messages • The meta-analysis indicates that psychosocial interventions have the potential to reduce loneliness in the community-dwelling elderly population. • As confidence in the evidence is low, healthcare providers should only implement interventions that are, firstly, based on a sound theory of change and, secondly, subject to rigorous evaluation.


Background:
University life can be a particularly challenging phase in the development of young adults. Current research shows that mental disorders occur more frequently in students compared to workers of the same age. The coronavirus pandemic has exacerbated the problem. The TUDo! Study, done in cooperation with the FU Berlin, aimed to assess the health status of students at TU Dresden, with a focus on mental health.

Methods:
In 2020/2021 students at TU Dresden (excluding students in the medical school) completed an online-based questionnaire. Validated questionnaires, e.g. the PHQ 4 (depressive disorder and generalized anxiety disorder) and the ERI student (student gratification crisis) were used. We evaluated descriptively and analytically, according to the questionnaire-specific specifications.

Results:
A total of 2,683 students (12.3%) at the TU Dresden took part in the survey. The majority of study participants were female (n = 1,507; 56.7%) and had an average age of 22.9 years (SD = 4.3). 32.8% (n = 856/2,611) of the participating students reported a depressive syndrome and 32.5% (n = 848/2,612) a generalized anxiety disorder. Almost half of participating students (40,0%; n = 515/1,310) indicated an imbalance between effort (E) and reward (R) (ER ratio>1). 51.23% (n = 693/1,50) of respondents reported a decline of mental well-being because of the coronavirus pandemic.

Discussion:
Unlike similar studies, this study shows that TU Dresden students were particularly affected with regards to perceived psychological stress and complaints. The existing differences seem to be partly due to the coronavirus pandemic. These results indicate that universities should regularly check their studying conditions and provide appropriate preventive measures. Key messages: Students are at higher risk than workers of the same age for mental health problems. Students reported a decline in mental well-being due to the coronavirus pandemic.
